Study on the Spillover Effects of Overseas Brand Crises  [PDF]
Qing Li, Zheng Jiang
Journal of Service Science and Management (JSSM) , 2017, DOI: 10.4236/jssm.2017.104031
Abstract: Innocent domestic brands are always infected by some overseas brand crises. In this article, we examined the factors that can inhibit the spillover effects of overseas brand crises. The results revealed that high level of mental construal and national identity can help domestic brands defend the negative spillover effects of overseas brand crises. For consumers with low level of national identity, they evaluate domestic brands more favorably when they are at the high level of construal than assigned at the low level of construal.
A Personalized Recommendation Algorithm Based on Associative Sets  [PDF]

Journal of Service Science and Management (JSSM) , 2009, DOI: 10.4236/jssm.2009.24048
Abstract: During the process of personalized recommendation, some items evaluated by users are performed by accident, in other words, they have little correlation with users’ real preferences. These irrelevant items are equal to noise data, and often interfere with the effectiveness of collaborative filtering. A personalized recommendation algorithm based on Associative Sets is proposed in this paper to solve this problem. It uses frequent item sets to filter out noise data, and makes recommendations according to users’ real preferences, so as to enhance the accuracy of recommending results. Test results have proved the superiority of this algorithm.
Pace of Expansion and FDI Performance: The Case of Auto FDIs in China  [PDF]

How fast do firms expand in a foreign market after their initial entry? Is faster better? Under what conditions is it beneficial or detrimental for a firm to move fast in a foreign market? This paper attempted to answer these questions by investigating the relationship between a firm’s pace of post-entry foreign expansion and its market share performance in a foreign market. The study is an attempt at filling a gap in the existing international business literature. Numerous researches have studied various point-of-entry decisions such as why (motivations), how (entry modes), where (location choices), and when (entry timing) firms make foreign entries. Studies have also investigated the consequences of internationalization, i.e., the relationship between degree of internationalization and firm performance. However, little is known about what happens after initial entry into a foreign market and before firms reach a certain degree of international diversity. As a step towards understanding the internationalization process, this study explores one important characteristic of post-entry foreign expansion—pace of expansion and its performance implications. Opposing hypotheses are developed from the perspectives of industrial organizational economics, and that of organizational learning, the resource-based view of the firm, and internationalization theory. The post-entry experiences of 214 foreign firms in China’s automobile market were examined in our sample. Results from multivariate regression show that greater firm performance is associated with greater expansion frequency and expansion magnitude. Furthermore, we found the inverted U shape relationship between expansion frequency and firm performance. J-shaped relationship between expansion magnitude and firm performance was also identified. We conclude this paper with implications for theory, research and management practice.

Calorimetric Measurements of CuAlNi Alloys

材料科学技术学报 , 1995,
Abstract: The martensitic transformation of CuAlNi single crystals is measured by DSC (differential scanning calorimeter). An isothermal single interface DO3→2H transformation arises when the specimen is quenched at a slow rate, but 2H→DO3 transformation always proceeds with multiple interfaces due to the existence of stored elastic energy inside martensite. The elastic energy is essentially stored on the martensitic interfaces and results in As→Mf, which brings a separate spectrum of heat flow on the measured curve. The size of stored elastic energy affects the hysteresis
Magnetic influence on the frequency of the soft-phonon mode in the incipient ferroelectric EuTiO3
Qing Jiang,Hua Wu
Physics , 2002, DOI: 10.1063/1.1540226
Abstract: The dielectric constant of the incipient ferroelectric EuTiO$_3$ exhibits a sharp decrease at about 5.5K, at which temperature antiferromagnetic ordering of the Eu spins simultaneously appears, indicating coupling between the magnetism and dielectric properties. This may be attributed to the modification of the soft-phonon mode, $T_{1\mu}$, which is the main contribution to the large dielectric constant, by the Eu spins(7$\mu_B$ per Eu). By adding the coupling term between the magnetic and electrical subsystems as $ -g\sum\limits_l {\sum\limits_{< {i,j}} {q_l^2}} \overrightarrow {S_i} \cdot \overrightarrow {S_j} $ we show that the variation of the frequency of soft-phonon mode depends on the spin correlation between the nearest neighbors Eu spins and is substantially changed under a magnetic field.
On black hole spectroscopy via quantum tunneling
Qing-Quan Jiang
Physics , 2012,
Abstract: In recent work [\emph{Quantum tunneling and black hole spectroscopy, Phys. Lett.} B686 (2010) 279, arXiv:0907.4271, by Banerjee et al.], it has been shown, in the tunneling mechanism, the area spacing parameter of a black hole horizon is given by $\gamma=4$. In this paper, by carefully analyzing the tunneling process of the black hole radiation, we interestingly find that the most qualified candidate for a universal area gap in the tunneling mechanism is $\gamma=8\pi$. First, we develop the Banerjee's treatment and the Kunstatter's conjecture to revisit the black hole spectroscopy via quantum tunneling, and find for a real tunneling process, the area spacing parameter is given by the possible value $\gamma\geq 4$. That is, the previous model-dependent area spacing parameters, i.e. $\gamma=8\pi, 4\ln 3, 4$, are all possible in the tunneling mechanism. Finally, some discussions are followed to find, in the tunneling mechanism, $\gamma=8\pi$ is the most qualified candidate for a universal area spacing parameter.

Revisit emission spectrum and entropy quantum of the Reissner-Nordstr?m black hole

Abstract: Banerjee and Majhi's recent work shows that black hole's emission spectrum could be fully reproduced in the tunneling picture, where, as an intriguing technique, the Kruskal extension was introduced to connect the left and right modes inside and outside the horizon. Some attempt, as an extension, was focused on producing the Hawking emission spectrum of the (charged) Reissner-Nordstr\"{o}m black hole in the Banerjee-Majhi's treatment. Unfortunately, the Kruskal extension in their observation was so badly defined that the ingoing mode was classically forbidden traveling towards the center of black hole, but could quantum tunnel across the horizon with the probability $\Gamma=e^{-\pi \omega_0/\kappa_+}$. This tunneling picture is unphysical. With this point as a central motivation, in this paper we first introduce such a suitable Kruskal extension for the (charged) Reissner-Nordstr\"{o}m black hole that a perfect tunneling picture can be provided during the charged particle's emission. Then, under the new Kruskal extension, we revisit the Hawking emission spectrum and entropy spectroscopy as tunneling from the charged black hole. The result shows that the tunneling method is so universally robust that the Hawking blackbody emission spectrum from a charged black hole can be well reproduced in the tunneling mechanism, and its induced entropy quantum is a much better approximation for the forthcoming quantum gravity theory.
Boundary expansions for minimal graphs in the hyperbolic space
Qing Han,Xumin Jiang
Mathematics , 2014,
Abstract: We study expansions near the boundary of solutions to the Dirichlet problem for minimal graphs in the hyperbolic space and characterize the remainders of the expansion by multiple integrals. With such a characterization, we establish optimal asymptotic expansions of solutions with boundary values of finite regularity and demonstrate a slight loss of regularity for nonlocal coefficients.
